Better to Keep Your Mouth Shut?

Have you ever said something you wish you could take back? Even as you heard yourself saying it, you were thinking, "This is probably not going to turn out well." But you said it anyway. And of course it didn't turn out well at all. So you say to yourself, "I'm just going to keep my mouth shut from now on." But you are never able to do that either. So what's the right thing to do? Speak up and push into issues that you know will be uncomfortable and cause pain but probably also bring tremendous growth? Or just sit there and keep your mouth shut...watching it all waste away into apathy and nothingness? (Well ok, maybe it's not that bad, but that's certainly how it can feel at times!) I need wisdom when it comes to controlling what I say and don't say every single moment of every single day. My mouth can be one of my greatest assest, but it can also lead to some of my worst nightmares. I suppose one thing I can do is to ask God for wisdom. To pray before I speak and ask God if what I'm going to say needs to be said in the way I'm planning on saying it at the time I'm planning on saying it. And then I need to stop talking long enough to listen for His voice to lead me on...
